Are those 3 steps a leftover from older versions where the agents would keep attaching? For some cold backup?
Your symptoms sound like some client attaches automatically (or perhaps a persistent user kept trying and happened to hit it just right), keeping you from shutting down. Check all your crons, including remote ones, and all scheduled jobs, and any oms. Didn't you have problems shutting dbconsole at one time? Those java processes can be maddening.
When you shutdown, you might want to have another sysdba session open, to check for what transactions are hanging it up. Sometimes an existing dbconsole session can help too.
Startup force does a shutdown abort and then startup. Both abort and force should only be used in unusual situations. I seem to be in the minority thinking an abort is dangerous, though. The general problem is, if you have any problems in your redo stream, you'll not be able to startup. I'm perhaps over sensitive about it, from the long ago days when standbys in recovery were delicate.
